OS X 10.10 Yosemite Local Development Environment: Apache, PHP, and MySQL with Homebrew

OS X 10.10 Yosemite comes with Apache and PHP pre-installed, but it's not in a great configuration, requires root to make lots of changes, and can introduce issues with file ownership and permissions. We prefer to use Homebrew to avoid these problems and because it's easier to keep up to date with newer versions of each component and extend customization. We can also set things up to be fully automatic so you can create new websites locally without needing to edit any configuration files.

With the arrival of Yosemite, some of the changes previously used in 10.9 for setting up Apache, PHP, and MySQL with Homebrew don't work quite the same. This guide will walk you through using Homebrew to install Apache, PHP, and MySQL for a "MAMP" development environment. We'll also use DNSMasq and Apache's VirtualDocumentRoot to set up "auto-VirtualHosts" so you don't need to edit configuration files when starting new projects. Finally, we'll add a firewall rule to allow the default http port 80 to be used without running Apache as root.

The following steps are intended for use on a Yosemite system without any previous attempts to use Homebrew for Apache, PHP, or MySQL. If you have attempted to install a similar stack and run into conflicts, or you've upgraded your operating system from 10.9 and things broke, the final section has some troubleshooting pointers. If that fails, leave a comment and I'll try my best to help you out.

At the conclusion of this guide, you'll be able to create a directory like ~/Sites/project and access it immediately at http://project.dev without editing your /etc/hosts file or editing any Apache configuration. We'll configure PHP and MySQL to allow for enough flexibility for development.

Because some of the commands span several lines, each command will be in a separate code block. This means you should copy and paste each code block in its entirety as a single command.

Before diving in, yes, this is a lot of steps. You can do it faster and pay money for something like MAMP Pro, but this is more fun, and you may learn something along the way! And, while you can simplify things with Vagrant or other virtual machine format, some people prefer to run things on "bare metal" and not have the overhead of a virtual machine.

Homebrew Setup

If you've not already installed Homebrew, you can follow the instructions at the bottom of http://brew.sh. I used to include the command in previous walkthroughs, but it could change after posting, so definitely always check their website to install it properly.

If you do not have git available on your system, either from Homebrew, Xcode, or another source, you can install it with Homebrew now (if you already have it installed, feel free to skip this step to keep the version of git you already have):

brew install -v git

PATH Variable

In previous guides on 10.9 and earlier, I added a change to $PATH in ~/.bash_profile to ensure that Homebrew-installed applications would run by default over similar ones that were already installed on OS X. Thankfully, Yosemite's $PATH order is different than earlier OS versions and now includes the default Homebrew location of /usr/local/bin in front. If you installed Homebrew to a custom location, or are not seeing /usr/local/bin at the beginning of your shell's $PATH, check out the file /etc/paths or the directory /etc/paths.d/.

MySQL

Install MySQL with Homebrew:

brew install -v mysql

Copy the default my-default.cnf file to the MySQL Homebrew Cellar directory where it will be loaded on application start:

cp -v $(brew --prefix mysql)/support-files/my-default.cnf $(brew --prefix)/etc/my.cnf

This will configure MySQL to allow for the maximum packet size, only appropriate for a local or development server. Also, we'll keep each InnoDB table in separate files to keep ibdataN-type file sizes low and make file-based backups, like Time Machine, easier to manage multiple small files instead of a few large InnoDB data files. This is the first of many multi-line single commands. The following is a single, multi-line command; copy and paste the entire block at once:

cat >> $(brew --prefix)/etc/my.cnf <<'EOF'

# Echo & Co. changes
max_allowed_packet = 1073741824
innodb_file_per_table = 1
EOF

Uncomment the sample option for innodb_buffer_pool_size to improve performance:

sed -i '' 's/^#[[:space:]]*$innodb_buffer_pool_size$/\1/' $(brew --prefix)/etc/my.cnf

Now we need to start MySQL using OS X's launchd, and we'll set it to start when you login. First, create the ~/Library/LaunchAgents folder if it doesn't already exist, copy the startup plist into it, and then start MySQL:

[[ ! -d ~/Library/LaunchAgents ]] && mkdir -v ~/Library/LaunchAgents

ln -sfv $(brew --prefix mysql)/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/

launchctl load -Fw ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

By default, MySQL's root user has an empty password from any connection. You are advised to run mysql_secure_installation and at least set a password for the root user:

$(brew --prefix mysql)/bin/mysql_secure_installation

Apache

Start by stopping the built-in Apache, if it's running, and prevent it from starting on boot. This is one of very few times you'll need to use sudo:

sudo launchctl unload /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

The formula for building Apache is not in the default Homebrew repository that you get by installing Homebrew. While we can use the format of brew install external-repo/formula, if an external formula relies on another external formula, you have to use the brew tap command first. I know, it's weird. So, we need to tap homebrew-dupes because "homebrew-apache/httpd22" relies on "homebrew-dupes/zlib". Whew:

brew tap homebrew/dupes

A slight deviation from my prior walkthroughs: we'll install Apache 2.2 with the event MPM and set up PHP-FPM instead of mod_php. If those terms mean anything to you and you're curious as to why I decided to go this route; it's because: 1) switching PHP versions is far easier with PHP-FPM and the default 9000 port instead of also editing the Apache configuration to switch the mod_php module location, and 2) if we're therefore not using mod_php, we don't have to use the prefork MPM and can get better performance with event or worker. As to why I'm using 2.2 instead of 2.4, popular FOSS projects like Drupal and WordPress still ship with 2.2-style .htaccess files. Using 2.4 sometimes means you have to set up "compat" modules, and that's above the requirement for a local environment, in my opinion.

Onward! Let's install Apache 2.2 with the event MPM, and we'll use Homebrew's OpenSSL library since it's more up-to-date than OS X's:

brew install -v homebrew/apache/httpd22 --with-brewed-openssl --with-mpm-event

In order to get Apache and PHP to communicate via PHP-FPM, we'll install the mod_fastcgi module:

brew install -v homebrew/apache/mod_fastcgi --with-brewed-httpd22

To prevent any potential problems with previous mod_fastcgi setups, let's remove all references to the mod_fastcgi module (we'll re-add the new version later):

sed -i '' '/fastcgi_module/d' $(brew --prefix)/etc/apache2/2.2/httpd.conf

Add the logic for Apache to send PHP to PHP-FPM with mod_fastcgi, and reference that we'll want to use the file ~/Sites/httpd-vhosts.conf to configure our VirtualHosts. The parenthesis are used to run the command in a subprocess, so that the exported variables don't persist in your terminal session afterwards. Also, you'll see export USERHOME a few times in this guide; I look up the full path for your user home directory from the operating system wherever a full path is needed in a configuration file and "~" or a literal "$HOME" would not work. This is all one command, so copy and paste the entire code block at once:

(export USERHOME=$(dscl . -read /Users/`whoami` NFSHomeDirectory | awk -F"\: " '{print $2}') ; export MODFASTCGIPREFIX=$(brew --prefix mod_fastcgi) ; cat >> $(brew --prefix)/etc/apache2/2.2/httpd.conf <<EOF

# Echo & Co. changes

# Load PHP-FPM via mod_fastcgi
LoadModule fastcgi_module ${MODFASTCGIPREFIX}/libexec/mod_fastcgi.so

<IfModule fastcgi_module>
FastCgiConfig -maxClassProcesses 1 -idle-timeout 1500

# Prevent accessing FastCGI alias paths directly
<LocationMatch "^/fastcgi">

FastCgiExternalServer /php-fpm -host 127.0.0.1:9000 -pass-header Authorization -idle-timeout 1500
ScriptAlias /fastcgiphp /php-fpm
Action php-fastcgi /fastcgiphp

# Send PHP extensions to PHP-FPM
AddHandler php-fastcgi .php

# PHP options
AddType text/html .php
DirectoryIndex index.php index.html
</IfModule>

# Include our VirtualHosts
Include ${USERHOME}/Sites/httpd-vhosts.conf
EOF
)

We'll be using the file ~/Sites/httpd-vhosts.conf to configure our VirtualHosts, but the ~/Sites folder doesn't exist by default in newer versions of OS X. We'll also create folders for logs and SSL files:

mkdir -pv ~/Sites/{logs,ssl}

Let's populate the ~/Sites/httpd-vhosts.conf file. The biggest difference from my previous guides are that you'll see the port numbers are 8080/8443 instead of 80/443. OS X 10.9 and earlier had the ipfw firewall which allowed for port redirecting, so we would send port 80 traffic "directly" to our Apache. But ipfw is now removed and replaced by pf which "forwards" traffic to another port. We'll get to that later, but know that "8080" and "8443" are not typos but are acceptable because of later port forwarding. Also, I've now added a basic SSL configuration (though you'll need to acknowledge warnings in your browser about self-signed certificates):

touch ~/Sites/httpd-vhosts.conf

(export USERHOME=$(dscl . -read /Users/`whoami` NFSHomeDirectory | awk -F"\: " '{print $2}') ; cat > ~/Sites/httpd-vhosts.conf <<EOF
#

)

You may have noticed that ~/Sites/ssl/ssl-shared-cert.inc is included multiple times; create that file and the SSL files it needs:

(export USERHOME=$(dscl . -read /Users/`whoami` NFSHomeDirectory | awk -F"\: " '{print $2}') ; cat > ~/Sites/ssl/ssl-shared-cert.inc <<EOF

Start Apache

Start Homebrew's Apache and set to start on login:

ln -sfv $(brew --prefix httpd22)/homebrew.mxcl.httpd22.plist ~/Library/LaunchAgents

launchctl load -Fw ~/Library/LaunchAgents/homebrew.mxcl.httpd22.plist

Run with port 80

You may notice that httpd.conf is running Apache on ports 8080 and 8443. Manually adding ":8080" each time you're referencing your dev sites is no fun, but running Apache on port 80 requires root. The next two commands will create and load a firewall rule to forward port 80 requests to 8080, and port 443 requests to 8443. The end result is that we don't need to add the port number when visiting a project dev site, like "http://projectname.dev/" instead of "http://projectname.dev:8080/".

The following command will create the file /Library/LaunchDaemons/co.echo.httpdfwd.plist as root, and owned by root, since it needs elevated privileges:

sudo bash -c 'export TAB=$'"'"'\t'"'"'
cat > /Library/LaunchDaemons/co.echo.httpdfwd.plist <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

EOF'

This file will be loaded on login and set up the 80->8080 and 443->8443 port forwards, but we can load it manually now so we don't need to log out and back in:

sudo launchctl load -Fw /Library/LaunchDaemons/co.echo.httpdfwd.plist

PHP

The following is for the latest release of PHP, version 5.6. If you'd like to use 5.3, 5.4 or 5.5, simply change the "5.6" and "php56" values below appropriately.

Install PHP and PHP-FPM. Excluding snmp is a workaround for a problem specific to Yosemite:

brew install -v homebrew/php/php56 --with-fpm --without-snmp

Set timezone and change other PHP settings (sudo is needed here to get the current timezone on OS X) to be more developer-friendly, and add a PHP error log (without this, you may get Internal Server Errors if PHP has errors to write and no logs to write to):

(export USERHOME=$(dscl . -read /Users/`whoami` NFSHomeDirectory | awk -F"\: " '{print $2}') ; sed -i '-default' -e 's|^;$date\.timezone[[:space:]]*=$.*|\1 \"'$(sudo systemsetup -gettimezone|awk -F"\: " '{print $2}')'\"|; s|^$memory_limit[[:space:]]*=$.*|\1 512M|; s|^$post_max_size[[:space:]]*=$.*|\1 200M|; s|^$upload_max_filesize[[:space:]]*=$.*|\1 100M|; s|^$default_socket_timeout[[:space:]]*=$.*|\1 600|; s|^$max_execution_time[[:space:]]*=$.*|\1 300|; s|^$max_input_time[[:space:]]*=$.*|\1 600|; $a\'$'\n''\'$'\n''; PHP Error log\'$'\n''error_log = '$USERHOME'/Sites/logs/php-error_log'$'\n' $(brew --prefix)/etc/php/5.6/php.ini)

Fix a pear and pecl permissions problem:

chmod -R ug+w $(brew --prefix php56)/lib/php

Until this pull request is merged, set the location of php_ini in pear to $(brew --prefix)/etc/php/5.6/pear.conf:

pear config-set php_ini $(brew --prefix)/etc/php/5.6/php.ini system

The included Opcache extension will speed up your PHP environment dramatically, and it's already installed, but needs to be enabled. We'll also bump up the opcache memory limit:

If you're not using PHP 5.5 or 5.6 and wish to add the opcache extension: See https://gist.github.com/alanthing/7acb05bf3e3dfc972b86.

Finally, let's put the PHP-FPM launchd plist file in place and start PHP-FPM now:

ln -sfv $(brew --prefix php56)/*.plist ~/Library/LaunchAgents

launchctl load -Fw ~/Library/LaunchAgents/homebrew.mxcl.php56.plist

Optional: At this point, if you want to switch between PHP versions, you'd want to stop PHP-FPM by unloading the plist above, run brew unlink php56, repeat all of the above PHP steps for php55/php54/php53, and loading the new plist. No need to touch the Apache configuration at all!

DNSMasq

A difference now between what I've shown before, is that we don't have to run on port 53 or run dnsmasq as root. The end result here is that any DNS request ending in .dev reply with the IP address 127.0.0.1:

brew install -v dnsmasq

echo 'address=/.dev/127.0.0.1' > $(brew --prefix)/etc/dnsmasq.conf

echo 'listen-address=127.0.0.1' >> $(brew --prefix)/etc/dnsmasq.conf

echo 'port=35353' >> $(brew --prefix)/etc/dnsmasq.conf

Similar to how we run Apache and PHP-FPM, we'll symlink a launchd plist to ~/Library/LaunchAgents and start:

ln -sfv $(brew --prefix dnsmasq)/homebrew.mxcl.dnsmasq.plist ~/Library/LaunchAgents

launchctl load -Fw ~/Library/LaunchAgents/homebrew.mxcl.dnsmasq.plist

With DNSMasq running, configure OS X to use your local host for DNS queries ending in .dev:

sudo mkdir -v /etc/resolver

sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/dev'

sudo bash -c 'echo "port 35353" >> /etc/resolver/dev'

To test, the command ping -c 3 fakedomainthatisntreal.dev should return results from 127.0.0.1. If it doesn't work right away, try turning WiFi off and on (or unplug/plug your ethernet cable), or reboot your system.

Great! So, what did I do?

We set up Apache to run on boot on ports 8080 and 8443 with auto-VirtualHosts for directories in the ~/Sites folder and PHP-FPM via mod_fastcgi. The OS X firewall will forward all port 80 traffic to port 8080 and port 443 to port 8443, so we don't have specify the port number when visiting web pages in local web browsers or run Apache as root. MySQL is installed and set to run on boot as well. DNSMasq and some OS X configuration is used to direct any hostname ending in .dev to the local system to work in conjunction with Apache's auto-VirtualHosts.

What do I do now?

You shouldn't need to edit the Apache configuration or edit /etc/hosts for new local development sites. Simply create a directory in ~/Sites and then reference "http://" + that foldername + ".dev/" in your browser to access it.

For example, download Drupal 7 to the directory ~/Sites/firstproject, and it can then be accessed at http://firstproject.dev/ without any additional configuration. A caveat - you will need to uncomment the line in Drupal's .htaccess containing "RewriteBase /" to work with the auto-VirtualHosts configuration.

What if this "auto-VirtualHost" doesn't work for [other project]?

If you need to create a manual VirtualHost in Apache because the auto-VirtualHost does not work for your configuration, you will need to declare it before the auto-VirtualHosts if you're also going to use .dev as the TLD. Otherwise the auto-VirtualHost block will be accessed first. I have a commented-out sample for a manual VirtualHost entry in "~/Sites/httpd-vhosts.conf" you may use.

Troubleshooting

The commands above can be run on a fresh Yosemite system without issue as I've tested with fresh installs in VMware. Nearly every problem I've heard about has been related to upgrading from 10.9 or earlier, or switching to this style of setup from another or similar setup. The easiest thing to do would be to brew uninstall each component referenced above, delete all related config files in $(brew --prefix)/etc and ~/Library/LaunchAgents, and start over. If that's a bit heavy-handed, check each of the configuration files edited in this guide and look for duplicate entries or typos.

You can also check log files for error output:

Apache: $(brew --prefix)/var/log/apache2/error_log, or run httpd -DFOREGROUND and look for output
PHP-FPM: $(brew --prefix)/var/log/php-fpm.log
MySQL: $(brew --prefix)/var/mysql/$(hostname).err
DNSMasq: no log file, run dnsmasq --keep-in-foreground and look for output
